MON ORAIL TRACK SUSPENSION.

Application led July 30, 1925. Serial No. 46,992.

T0 all whom t may concern:

Be it known that I, RUSSELL E. NELLEs, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new Iand useful Improvements in Monorail Track Suspensions, of which the following is a specification.

This invention relates to improvements in monorail track suspension devices and the object in the present instance is to provide a track suspension in which the maximum of flexibility is obtained, and in which vertical and horizontal adjustment may be easily and rapidly obtained.

The invention contemplates a monorail system comprised of a standardl T-bar, a forked clevis pivotally attached to the bar, a hanger rod to support the clevis and the T-bar and a suitable ceiling fixture to which the upper end of the rod is attached to form va swivel connection between the ceiling fixture and the assembled suspension device.

The invention is more fully described in the following specification and clearly illustrated in the accompanying drawings, in which Figure l is a side view of my track suspension.

Figure 2 is an end view thereof, with the track and the ceiling fixture in section.

The. numeral l designates the track which is an ordinary standard Tbar the stem of which is formed with a series of perforations 2, bored at right angles to the stem.

The numeral 3 designates a clevis, which vis formed with a bifurcated lower portion 4, the lower extremities of the bifurcated portion being' formed with a threaded opening` to receive the clevis pin 5, which will provide the desired pivotal connection between the clevis and the track, and which will assure a double shear on the clevis pin when subjected to a load.

The upper portion or body of the clevis, 3, is formed with a vertical threaded opening. The numeral 6 designates a supporting rod, the lower end of which is threaded to accommodate the threaded opening in the clevis, and the clevis is vertically adjustable on the said rod, thus providing the desired vertical adjustment for the track. The rod is provided with a nut and a split washer l1, for securing the parts when adjusted. The upper end of the rod is formed with a head 7 and the rod is rockably mounted in a ceiling fixture 8, which is formed with a hole` for the rod to pass through while the head rests against the inner surface of the fixture, thus forming a swivel for the entire structure. The ceiling fixture is secured to the overhead structure 9 by lag screws 10 or other suitable means.

The structure thus described will provide the much desired pivotal connection between the track and the clevis, the desired swivel connection between the entire device and the supporting structure and the longitudinal adjustability of the track on the clevis members, because of the series of perforations in the T-bar stem.

The structure as defined is extremely simple, while the strength of the parts and of the assembly are very great.

What I claim is 1. In a'monorail track suspension, a supporting member, means for securing it to an overhead structure, a threaded, supporting rod depending therefrom and rockably held therein, a clevis vertically adjustable on the rod, said clevis having a bifureated lower portion formed with perforations, a T-bar having a series of perforations, and a clevis pin securing the bifurcated end of the clevis to the T-bar in pivotal connection.

2. In a track suspension, a perforated T-bar, a bifurcated clevis pivotally secured thereto, a threaded supporting rod on which the clevis is vertically adjustable, a head on the rod and aceiling fixture in which the rod is rockably held while supporting the clevis and T-bar.

In a track suspension, a track having a series of perforations in the stem thereof, a bifurcated clevis pivota-lly attached to the track by a clevis pin at one of the perforations, a supporting rod for the track and clevis having a threaded lower end adapted for engagement by the clevis to provide vertical adjustment of the track, said rod being suspended from a ceiling fixture rockably.

In testimony whereof I aliix my signature.

RUSSELL E. NELLES.
